The Oprah Winfrey Show and QVC are looking for the next great invention.
QVC is sponsoring three national trade shows in Chicago, Philadelphia and Los Angeles during March, from which up to 10 finalists will get the opportunity to present their invention on Oprah.
The studio audience will vote for their favorite, and the winning invention will be featured on QVC.
The official rules are available on the Web sites of The Oprah Winfrey Show and QVC.
